We were having a lot of houseguests for Thanksgiving. The spare bed is a futon, which many people find uncomfortable we also have 2 air mattresses, which can be cold and hard. We got 3 of these synthetic featherbeds, hoping they would help -- and they did! Everyone found their beds very comfortable (for a change). I definitely recommend these mattress toppers and I enthusiastically recommend buying them from Wayfair, which shipped fast!
